v1.9.3

What's Changed

• Fixes a bug in WriteBuffer#shiftBytesLeft by @zslayton in #416

Full Changelog: v1.9.1...v1.9.3

v1.9.2

Reverts 1.9.1 due to regression found in #416. This release is functionally equivalent to 1.9.0.

v1.9.1

Please note, as per #416, non-default pre-allocation configuration for the IonWriter can cause corruption in certain cases, it is recommended that you do not use this release.

Features

• Adds members to the IonNumber interface and makes IonDecimal, IonFloat, and IonInt implement IonNumber (#400)
• Performance improvements
  • Compacts preallocated headers when possible (#401)
  • Eliminates allocations in the binary writer (#404)
  • Backs Pool with ConcurrentLinkedQueue instead of ArrayBlockingQueue (#405)
  • Optimizes the incremental reader's symbol table reading logic for tables with imports. (#407)
  • Enables the incremental reader to iterate annotations lazily. (#408)
  • Properly sizes the buffer when a fixed-size stream is provided to the incremental reader with default configuration. (#410)

Fixes

• Fixes Ion Binary Reader to fail fast when an IVM type code is encountered in an illegal position (#397)
• Adds explicit narrowing casts in Timestamp (#411)

List of commits: v1.8.3...v1.9.0

v1.9.0

Features

• Added a new binary reader implementation that speeds up reads by up to 50% and allows for data to be parsed incrementally from a growing InputStream. To enable the new reader implementation, use IonReaderBuilder.withIncrementalReadingEnabled. (#355)
• Added an IonSystemBuilder option (IonSystemBuilder.withReaderBuilder) that allows users to specify an IonReaderBuilder to be used to construct any IonReaders needed by IonSystem’s methods (newReader, iterate, singleValue, and IonLoader.load via IonSystem.getLoader or IonSystem.newLoader). This may be used, for example, to use the new incremental binary reader to read binary Ion data into its IonValue representation. (#385)

Fixes

• Added a pool of reusable UTF-8 decoders to be used by both binary reader implementations, making repetitive instantiation less expensive. (#388)
• Eliminated the use of ConcurrentLinkedQueue.size() in the binary writer’s block pool, improving writer performance when the pool gets large. (#389)

List of commits: v1.8.3...v1.9.0

v1.8.3

Fixes

• Fixed handling of NaN and +/-Inf when downconverting to json.

Features

• Made writeValueRecursively iterative. (#368)
• Adds a pool of UTF8 String encoders. (#369)
• Adds GitHub workflow to detect the performance regression of ion-java automatically. (#373)

List of commits: v1.8.2...v1.8.3

v1.8.2

Fixes

• Removed an assertion that could be violated when an invalid text encoding was encountered; replaced with IonException. (#357)
• Sped up modifications of deeply-nested IonValues by up to 40% by adding a reference to IonSystem within IonContainer. This change also prevents a potential StackOverflowError when working with deeply-nested containers. (#361)
• Reduced the CPU time, heap allocations, and garbage collection time required to instantiate binary writers by up to 70% by making PooledBlockAllocatorProvider a singleton. (#363)

List of commits: v1.8.1...v1.8.2

v1.8.1

Fixes

• Catches exception of unknown SIDs that bigger than INT_MAX. (#349)

Features

• Add option to configure whether top level values should be delimited by newlines in an Ion Datagram; Add option to configure what line separator (eg. LF, CR+LF, etc) should be used (#351)

List of commits: v1.8.0...v1.8.1

v1.8.0

Fixes

• Fixes a bug in IonReaderBinaryRawX.readBytes (#318).
• Avoids repetitive reallocation of PooledBlockAllocatorProvider in _PrivateIon_HashTrampoline.
